Abstract (en)
Synchronizing between multiple optical data can be maintained by a facilitated method. An operational unit 108 including: an optical data obtaining part 301 which obtains a laser scan point cloud obtained by a laser scanner mounted on a moving body in a moving condition and image data of a photographed image photographed by a camera mounted on the moving body in a moving condition; a correspondence relationship determining part 307 which determines correspondence relationship between point cloud image of which the laser scan point cloud is viewed from a specific viewpoint and the photographed image; a camera position and orientation calculating part 308 which calculates camera position X<sub>1</sub> in photographing of the photographed image by a single photograph orientation based on the correspondence relationships; and a delay time (Δt) calculating part 309 that calculates Δt when the camera photographs with a delay Δt when the camera is commanded to take a photograph at a time T, in which the Δt is calculated based on a difference of the time T<sub>1</sub> corresponding to the camera position X<sub>1</sub> and the time T.
